Good question.
I don't know enough about how we handle the PKs to answer it.
- Do we store the PK field(s) in actual cell, or are they only present in
the rowkey ?
- What happens when you specify a CF for a PK field ? is it even valid ?
This should be easy enough to check with hbase shell.
I'll try to check later today if you can't answer these of the top of your
head.
